Innovative antimicrobial substances based on uracil S-derivatives

Area of Science:

• Medicinal Chemistry
• Organic Synthesis
• Microbiology

Background:

• Antimicrobial resistance poses a significant global health threat.
• Natural products serve as a foundation for developing new antibiotic compounds.
• Uracil derivatives are explored for their potential in treating infectious diseases.

Purpose of the Study:

• To synthesize novel uracil S-derivatives.
• To evaluate the in vitro antimicrobial properties of these new compounds.
• To investigate structure-activity relationships for enhanced antibiotic development.

Main Methods:

• Synthesis of N3-(thietan-3-yl)- and N3-(1,1-dioxothietan-3-yl)uracil derivatives.
• Alkylation and hydrazinolysis to form acetohydrazides.
• Antimicrobial activity testing using the agar diffusion method against a panel of bacteria.

Main Results:

• Twelve new uracil S-derivatives were successfully synthesized.
• N-acyl-5-hydroxypyrazolines and N,N'-diacylhydrazines exhibited high antimicrobial activity.
• Minimum inhibitory concentrations (MIC) ranged from 0.1 to 10 μg/ml.

Conclusions:

• The synthesized uracil derivatives demonstrate significant potential as novel antimicrobial agents.
• Modification of natural product scaffolds like uracil is a viable strategy against antimicrobial resistance.
• Further development of these compounds could lead to new therapeutic options for bacterial infections.
